WOVEN FABRIC AND METHOD OF WEAVING THE SAME.

Application filed June 20, 1914.

To all whom it may concern:

Be it known that 1, CHARLES GORDON Barns, a subject of Great Britain, residing at London, England, have invented a certain new and useful Improvement in VVover. Fabrics and Methods of Weaving the Same, of which the following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to multiple-ply woven fabrics having as produced in a loom, the different plies thereof united and combined in the form of pockets, and further relates to the method of weaving fabrics of such class.

The invention consists in a new fabric structure, and a novel method of weaving the same, the result being a novel pocketfabric. More especially, the improvement in the fabric-structure resides in the manner in which the warp-threads, in sets or groups as hereinafter explained, are interwoven with the weft-thread in forming the external wall, one or more partitions, and the bottoms to the pocket-compartments.

The pocket-fabric which is produced in accordance with my invention comprises a backing ply, from the face of which projects a wall which constitutes the two ends as well as the front of the pocket, the weaving being so conducted as to form a plicated or bellows-bottom comprising one or more inwardly directed folds, with one or more longitudinal partitions or septa, each having its inner portion joined to the apex of an inwardly-extended bottom fold and its ends joined to the end walls of the pocket and with the fold-members relatively inclined to each other and also connected with the end-walls on oblique lines so that approximately V-shaped web-portions of the endwalls are formed between the said foldmembers eXteriorly of the bottom fold or folds. My invention provides for the whole pocket being woven integral and in a single continuous process. In the weaving process, the warp-threads are operated in groups for the formation of the backing, and of the end walls and the front, as well as in other groups for the formation of one part of each inwardly directed bottom fold, the formation of a partition, and that of the other part of each bottom fold.

threads in these groups. are or may be embodied in the backing until the weaving or the pocket commences. The groups of warp-threads are then selected in turn, the threads in some of these groups being atfirst selected sometimes in succession and sometimes simultaneously, and picks of weft are taken through them so as to form .the various parts in order. Subsequently, when the weaving of the pocket is finished, all

the warp-threads are or may be again thrown into the backing. The latter, when a pocket is not being formed, may be made as a two-ply fabric, the plies of which may be connected together at intervals, and between which plies some or all of the warpthreads not of necessity employed in the formation of the backing may be floated.

In the accompanying drawings, Figure 1 is a perspective view, partly broken away,

of a fabric woven in accordance with this invention. Fig. 2. is a perspective view showing a transverse section of the said fabric taken on the line 22 of Fig.1.

Like letters indicate likeparts throughout the drawings. 7

A is the backing from which spring the two parts B, B, forming the end walls of the pocket, these walls being joined by the front wall G which lies substantially parallel to the backing A. Between the end walls B, B, run two longitudinal partitions D and E which are substantially parallel to the backing A and the front wall 0. The lower edge of each partition joins an inwardly directed bottomfold, a series of folds forming the bottom of the pocket. The partition D is joined with the two relatively inclined parts F, G, forming one inwardly directed bottom fold, and the bottom of the partition E is joined to two relatively inclined parts H, J, forming the second inwardly directed bottom-fold. The lower edge of the part F is united to the lower part of the backing A. The lower warp-threads are operated in groups to pro duce the various parts thereof, namely the backing A, the end walls B together with' the front wall C, the partition D, the partition E, and the several fold-members F, G, H, J. Initially, before actually commencing the formation of the pocket, the warpthreads are interwoven to produce a webportion A and if desired with the warpthreads which are not necessary to the formation of the said web-portion confined between the plies of the latter. After a sufficient length of web-portion A has been woven in this way, the weaving of the pocket is commenced by first throwing out from those warp-threads necessary for the formation of the backing all the other warpthreads comprised. in the above mentioned groups. The pocket of the particular fabric that is to be hereinafter described, and that is illustrated in the drawings by way of example, is provided with two partitions and is thus formed with three compartments.

All the warp-threads which were thrown out from those pertaining to the backing are employed in commencing the weaving of the part B of the first end wall B of the pocket. As the weaving of such part proceeds, the warp-threads of the group intended for use in the weaving of the part F of the first inwardly directed bottom fold are successively thrown out of operation. By reason of the number of warp-threads employed in the weaving of the part B, it will be appreciated, as somewhat diagrammatically shown in thedrawings, that this part B of the first end wall is thicker than other portions of the said end wall. The normal thickness, as it may be termed, appears at the upper part of this wall, which conveniently extends above the upper edges of the partitions. At a suitable stage dependent on the dimensions which are desired for the seve'al compartments of the complete pocket, the group of warp-threads intended for use in the formation of the first partition D are thrown out of opera tion, while the weaving of the end wall is continued. The warp-threads for forming the fold-member G are thrown out in succession or in successive sets as the weaving of the end wall progresses. By the omission of these warp threads of partition D and fold-member G the thickness of the part B of the first end wall is reduced. As the weaving of this end wall progresses the small group of warp-threads intended for use in the formation of the fold-member H are thrown out successively. Next, the warp-threads intended to be used in the formation of the partition E are all thrown out simultaneously, and the warp-threads for weaving the fold-member J are thrown out either successively or in successive sets. The weaving of the first end wall B is now continued, the thickness of this end wall now being reduced to the normal, and the weaving of this end wall goes on until the end wall has attained the required dimensions.

It is to be noted that the described pro cedure in weaving will result in the production of approximately ll-shaped portions of the end wall, as appears in Fig. 2 of the drawings, between the fold-members, not only on the inside of the pocket but also outside the fold-members, at the bottom of r the pocket. Picks of weft are now taken in suitable sequence through the several groups of warp-threads, namely those forming the backing A, those forming respectively the fold-members F, G, H and J, those forming the partitions D and E, and finally those forming the outer wall C of the pocket. The weaving of all these parts is practically simultaneously carried out by successive picks through the different groups of warpthreads in such a way that the lower edge of the fold-member F is united to the back ing toward the lower edge of the latter, the upper edges of the fold-members l and a} are united to the lower edge of the partition D, the lower edges of the fold-members G and H are joined, the upper edges of the fold-members H and J unite with the lop-er edge of the partition E, and finally the lower edge of the fold-member J oins the lower edge of the outer wall 0. Prefera ily, the lower part of the outer wall C is slightly gathered in where it joins the lower edge of the fold-member J, a fullness being thus given to the outer compartment of the pocket.

When the backing, partitions, inwardly directed folds, and front wall, have all been woven to the extent necessary to produce a pocket of the desired length the various groups of warp-threads are in turn thrown back into the second end wall as the weaving of the latter progresses. The groups of warp-threads are thrown back into the end wall in the reverse order to that in which they were thrown out in the formation of the first end wall B and its parts B, The warp -threads employed in forming each partition are thrown back or enter again simultaneously in groups into the mation of the second end wall, while the warp-threads which have been employed in the formation of the fold-members return into the end wall either in succession or in successive sets in the same way as they were initially thrown out in the formation of the first end wall. Finally, all the groups warp -threads employed in weaving th pocket enter again into the body-web a: u are subsequently floated or otherwise dealt with in this body-web as found convenient,

The warp-threads employed in the formation of the bottom folds are preferably thrown out and subsequently returned to the end walls by all the threads in some groups being thrown out simultaneouslyv and returned in the same way, while the threads in other groups are thrown out in succession or in successive sets and subsequently returned in the same way. The bottom folds may however in some cases be formed by throwing'out successively or in successive sets the threads in each group, these threads being similarly returned into the second end wall when the weaving of the pocket is nearing completion. The formation of the bottom fold of the pocket by the successive throwing out of the warpthreads, that is to say not only in successive groups but successively as regards individual threads or sets of threads, constitutes an important feature in the construc-. tion of the pocket in that it results in each chamber or division of the completed pocket having such dimensions as will allow sufficient room for the intended contents. Thus in the case of a cartridge pocket, the latter will allow sufficient room for the cartridges it is to contain without these cartridges being too close a fit in either compartment of the pocket. Further, the whole bottom of the pocket is so formed that water enter ing it can drain away and does not collect in a mass of woven material, since by reason of the formation of the bottom of the pocket it is of practically uniform thickness with no accumulation of threads or gathered in or thick material which would tend to retain the wet and by swelling or shrinking up restrict the space provided for the cartridges.

It is to be noted that by the successive throwing out of the groups of warp-threads and by the successive throwing out of the threads or sets of threads making up any one of these groups the several parts of the bottom folds are caused to be inclined relatively to each. other, to the backing, and to the front wall. This relative inclination of the parts forming the bottom folds is assisted and insured by the picks of weft as they occur in proper sequence through the several groups of warp-threads.

The warp-threads for forming each partition are preferably all thrown out from the end wall simultaneously since it is desirable that the partition should be substantially vertically disposed in the pocket and practically parallel to the backing. In some cases however it may be desirable to form each partition with warp-threads thrown out successively or in successive sets from the end wall so that this partition will be inclined to the backing, and in this way additional space in the upper part of each pocket division may be obtained. The manner in which the warp-threads in any group may be thrown out or selected and subsequently returned may however vary as found desirable in accordance with the deis made deeper than heretofore,

tail construction of the pocket which is'to be formed. i

It is to be noted that the pocket produced as described constitutes a development of certain known constructions of pocket. Thus a pocket with longitudinal partitions in it has but in that case the lower edge of the front wall, together with the lower edge of the partition, went into the backing without fullness being provided such as is obtained by the inwardly directed fold or folds provided in the present construction. Again a pocket has been formed with a fold in the bottom which was adapted to be flattened out, thereby giving the bottom of the pocket a fullness which enabled it to receive a rectangular package which filled the whole pocket. This type .of pocket has again been modified by dividing it into cells or compartments, each of which was adapted to contain a rectangular package. In this case the pocket had an inwardly directed fold forming the bottom, which fold had to be flattened out in order to accommodate the packages. A longitudinal partition was employed in this pocket 1 together with transverse partitions, the longitudinal partition being woven with a longitudinal fold toward its lower end where it was connected to the apex of the bottom fold, this being necessary to allow of the fold in the bottom of the pocket being pushed down or H attened out.

In the present case it is to be noted that while the additional space required at the bottom of the pocket is obtained by provid ing inwardly directed folds, it is desirable that the apex of each of these folds should not be pushed downward or flattened out when the pocket is'filled. Hence this fold and by the successive throwing out and gathering up of the warpthreads in forming this fold so that the sides of the fold are inclined to one another as described the necessary fullness is obtained in the bottom. The apex or upper edge of the fold, for example, that formed by the fold-members H and J, is connected to a partition Ewhich runs directly upward therefrom, and practicallyv this through the connection of the ends of partition to the end wall B of the pocketthe partition E constitutes a support for the bottom fold H, J. The construction is such also that the bottom of each chamber in the pocket "is smaller than the upper part of each of these chambers, and hence a group of cartridges in clips fits snugly into each pocket chamber or division, the bullets of the cartridges lying in lower end of each chamber and being to some extent gripped therein. tion in the size of the lower portion of each pocket chamber practically results from the previously been woven,

the somewhat reduced This reduc necessary gathering in the base of each pocket during the process of weaving the in Wardly directed folds, the gathering in also as already mentioned being carried out at the lower edge of the outer wall of the pocket. The upper part of the pocket may also be made somewhat larger than the lower part by introducing extra or gusset picks at suitable intervals into the outer and end walls and if necessary also into the partitions.

It is convenient to provide a pocket woven in accordance with this invention with a slit or double edge A, A to the upper part of the backing A, this slit edge being formed in a known manner by weaving the plies of the backing separately for a certain distance inward from the edge.

It is obvious that pockets woven in accordance with this invention may be disposed in any number on a backing, or formed separately and detachably mounted on a backing or belt, or otherwise arranged as found convenient in the equipment with which they are intended to be used. As mentioned, the pocket made in accordance with my invention may have two or more partitions and thereby be adapted to take three or more groups of cartridges in clips. Preferably, it is constructed to contain three such groups, but it may be formed so as to hold more than three groups by providing extra groups of warp-threads, the process of weaving being substantially that already indicated. Further, the dimensions of the pocket divisions may vary. Thus, for example, the first or innermost division or chamber may be formed of such size as to permit of it containing two sets or groups of cartridges in clips, while each of the other divisions is made so as to hold only one set of cartridges.

Gopies of this patent may be obtained for five cents each, by addressing the What I claim is tinnous process a pocket-fabric having one or more longitudinal partitions connected to an expanding bottom formed by one or more inwardly directed folds, consisting in arranging the warp-threads in groups accord ing to the parts of the pocket in the formation of which they are to be employed, and successively throwing out and gathering up these groups of threads in the manner described, to produce the end-walls, partition or partitions, and front-wall, the individual threads in certain of these groups being also thrown out successively or in successive sets to produce the fold-members, picks of weft being in due course taken through these groups of warp-threads, whereby the several parts of the pocket are produced and the folds of the bottom are joined with the endwalls on oblique lines.

2. A woven fabric comprising a backing, front and end walls, one or more partitions and a plicated or bellows-bottom, with each partition springing from an inwardly directed bottom fold, and with each bottom fold formed by the successive throwing out of the warp-threads employed in its forma tion so that the fold-members are relatively inclined to each other and are connected. with the end-walls on oblique lines and have approximately \l-shaped web-portions of the end walls formed between them eXteriorly of the bottom fold or folds.
